Abstract
The invention relates to a sow raising and breeding method. Through the method, a disperse, random and traditional raising method is converted into concentrated, continuous and balanced assembly line production according to ecological and physiological characteristics of sows, an all-in and all-out process is implemented, and annual balanced production is performed according to the breeding rhythm. The key technology of all-in and all-out production according to the breeding rhythm is estrus synchronization. Estrus synchronization of the sows can be achieved through three methods, namely (1) estrus synchronization of the multiparous sows is achieved through a simultaneous weaning method; (2) estrus synchronization of the sows experiencing the puberty or pregnant sows is achieved through a pen breeding and hormone injection method; (3) estrus synchronization of gilts which are not in the puberty is achieved through a group raising and hormone injection method. The sow raising and breeding method is experience obtained through many years of sow raising, enables the sows to bred regularly, facilitates production and operation management, and enables work to be conducted in an orderly and planned mode.
Description
Technical field
The invention belongs to poultry cultivating technology, particularly a kind of boar cultivation mating system.
Background technology
Along with the raising of people's living standard, people are also more and more higher to the requirement of quality of the life, especially diet aspect.Large scale of pig farm has been a kind of trend now, arises at the historic moment in piggery of all sizes, and therefore the demand of piglet is increasing, and this has just proposed new requirement to boar industry.But boar industry faces the problem of two aspects at present:
1, due to the driving of market economy, the large-scale pig farm of China is more and more, and scale is increasing, and the demand of piglet is also increasing, but neither one boar breeding at present is scientific and normal, and each boar enterprise cultivates according to the experience of oneself;
2, its habits and customs of different boars and physiological period are variant, if biological control, management difficulty is larger.
Summary of the invention
The object of this invention is to provide a kind of scientific and normal, be applicable to boar and cultivate the new method of breeding.
A kind of boar cultivation mating system, the method is transformed into concentrated, continuous, balanced continuous productive process by the ecological physiology feature of pig dispersion, random, traditional raising method produces, and carries out all in all out technique processed, presses the annual balanced production of reproductive rhythm; Described all in all out system refers to the continuous-flow type production process that proceeds to simultaneously, produces simultaneously with a collection of swinery, produces by reproductive rhythm, and produce the whole year regardless of seasonal balancing.
Described all in all out, the key technology of producing by reproductive rhythm are estrus synchronizations.The concrete grammar of realizing estrus synchronization is:
(1) method that weans the same period for the childbirth nursing sow of 21～35 days, generally all can be oestrused in 4～7 days after wean, implements the wean same period for the approaching nursing sow of delivery time, can reach wean oestrus of sow synchronization.
(2) if sow has exceeded puberty or pregnant, can carry out pen-breeding 2 weeks to the sow that oestruses, after 2 weeks, to full group's injection Cloprostenol 200～300 micrograms, inject after hormone, pregnant sow can be miscarried simultaneously, and sow all can oestrus because of luteolysis simultaneously.
(3) sow pig that does not enter puberty is carried out to group support by every 6～8 for a group, rule of thumb predict the time that sow pig is oestrused for the first time, before sow pig is oestrused for the first time 20～40 days, every sow shot P.G.600, oestrus and do not breed, the 18th day injection Cloprostenol 200～300 micrograms, after 3 days, sow just shows and oestruses, and reach unanimity estrus time; If sow now body weight has reached breeding body weight, can arrange breeding.
the present invention boar mating system is by the experience that the cultivation to boar draws for many years, and this method both can make the regular breeding of boar, is convenient to again produce and management, and work can orderly, plannedly be carried out.
Embodiment
The present invention, according to the experience of raising pigs for many years, has drawn cultivation and the mating system of a set of boar, and the method is:
By the ecological physiology feature of pig, dispersion, random, traditional raising method are transformed into concentrated, continuous, balanced continuous productive process and produce, carry out all in all out technique processed, press the annual balanced production of reproductive rhythm.So-called all in all out system refers to the continuous-flow type production process that proceeds to simultaneously, produces simultaneously with a collection of swinery, produces by reproductive rhythm, and produce the whole year regardless of seasonal balancing.
The raising technology index of boar is:
1,2.34 tire/years, 10/tire, 7 obstetric tables in the sky in advance, wean, turn group, sterilization, empty hurdle 7 days for 21 days.
2, child care to 70 age in days, seed selection to 160 age in days (22 weeks), breeding parturition rate 85%, lactation survival rate 96%, child care survival rate 98%, boar mortality 35%, artificial insemination ratio 1:80, this double ratio example 1:25.
With 7 days production cycles, annual 52 weeks, 2500 boars were example below:
Year farrowing nest number: 2500 × 2.34=5850 nest
The nest of farrowing is weekly counted 5850/52=112 nest
A breeding number 112/85%=132 head weekly
Deliver weekly number pigs weaned 112*10*96%=1075 head for sale
Boar pig house is completely different from the pig house of common pork pig, and the pig house of boar is designed to:
Sow is 7 obstetric tables in the sky in advance, within 21 days, wean, turn group, and sterilization, empty hurdle 7 days, need 5 weeks altogether, 2 unit weekly, and 56 of every unit obstetric table, needs 10 unit altogether, 560 obstetric tables.
Ensure that in the present invention the boar key technology that can normally move of breeding is estrus synchronization, can ensure that like this work on pig farm is carried out in order, its concrete grammar is:
1, make multiparity sow estrus synchronization
Adopt the method that weans the same period: multiparity oestrus of sow synchronization, the simplest, the most the most frequently used method is the wean same period, for the childbirth nursing sow of 21～35 days, generally all can after wean, in 4～7 days, oestrus.Implement the wean same period for the approaching nursing sow of delivery time, can reach wean oestrus of sow synchronization object.
2, pregnant sow estrus synchronization after puberty or
If sow has exceeded puberty, can carry out pen-breeding 2 weeks to the sow that oestruses, after 2 weeks, full group is injected to Cloprostenol 200～300 micrograms.After injection hormone, pregnant sow can be miscarried simultaneously like this, and sow all can oestrus because of luteolysis simultaneously;
3, do not enter the estrus synchronization of the sow pig of puberty
Every 6～8 sow pigs are that a group is carried out group support, rule of thumb predict the time that sow pig is oestrused for the first time, before sow pig is oestrused for the first time 20～40 days, and every sow shot P.G.600.Oestrus and do not breed, the 18th day injection Cloprostenol 200～300 micrograms, after 3 days, sow just shows and oestruses, and reach unanimity estrus time.If sow now body weight has reached breeding body weight, just can arrange breeding.
In the present invention, the key technology of boar estrus synchronization is: grasp the time of sow puberty, if injection too early, sow does not reach yet for a long time the just feelings age after oestrusing, and no longer performance is oestrused; If injection too late, sow pig has entered the oestrous cycle (after puberty), and sow can not oestrus because of injection gonadotropin, just can not be tending towards the same period estrus time.
The advantage of boar mating system of the present invention is:
One, can reduce a number of sow to be joined and replacement gilt, because be 21 days the oestrus of pig, be 7 multiple;
Two, the technical work of breeding and work task arrange can be completed in one week 5 days, avoid Saturday or Sunday, because most of sows oestrus after wean (wean on Thursday) for 4th～6 days, breeding work can be arranged in three days and complete, as arranged breeding from Monday to Thursday, the number of deficiency can require to be supplemented by replacement gilt in accordance with regulations, can make like this breeding of producing and turn group's work all before Thursday, to complete.
Three, be conducive to by week, monthly and per year work out work plan, set up orderly work and holiday system, reduce confusion and the blindness of work.
